Quick-heating electric soldering iron heating head

Abstract

The quick heating electric iron is low in energy consumption, long in durability, heating the electric iron to the required temperature, with isolation base on the heating thread formed as the heating core, isolation layer outside the heating core, outside metal conductor outside isolation layer, end of the outside metal conductive body being the iron head, with the heating core, isolation layer, metal conductive body closely bonded together to form a seamless structure. There is a temperature sensor controlling the heating temperature on the heater, formed into the controllable temperature and quick heating electric heater. Between the outside metal conductor and isolation layer forms the link and quick conductive force of the inner metal conductor. The invention relates to a quick heating electric iron with quick heating speed, small in size, low in energy, long in durability, high in efficiency.

Description

technical field [0001] The invention relates to a heating head for a direct-heating fast-heating electric soldering iron, especially a heating head for a fast-heating electric soldering iron with low energy consumption and long service life, which can heat the electric soldering iron to a specified temperature within seconds , belongs to the technical field of electric soldering iron manufacturing. Background technique [0002] The electric heating type soldering iron is composed of a heating core, a heat conductor, a thermal head and auxiliary working parts such as handles and wires. During the process of heat conduction from the heating core through the heat conductor to the thermal head, it is subject to the strong thermal resistance of the thermal resistance interface composed of several air layers and different materials. The result is: [0003] 1. The temperature of the heating wire is too high. The metal heating wire works near the limit temperature and is in a hot s...

AI Technical Summary

Problems solved by technology

[0003] 1. The temperature of the heating wire is too high. The metal heating wire works near the limit temperature and is in a hot state.

[0004] 2. Large temperature difference heat conduction The temperature difference between the heating core and the thermal head is very large, the heat transfer efficiency is low, and the heat transfer is slow

[0005] 3. Severe oxidation reaction Due to poor heat conduction, the temperature of the heating wire is much higher than that of the thermal head and placed in the air, the oxidation reaction of the heating wire is severe

[0006] 4. The temperature rise of the thermal head is too slow. Due to the strong thermal resistance of the thermal resistance interface composed of several air layers and different materials, the thermal head reacts slowly and lags behind in control. Only by increasing the thermal head to store energy to meet the welding requirements. When the thermal energy needs to be continuously welded, it is often necessary to wait for the thermal energy to be replenished, which is a waste of copper and affects work efficiency.

[0007] To sum up, the traditional electric heating type soldering iron has large volume, high energy consumption, short life and low efficiency
